filter on gridbuttoncolumn

[Jean-Marc]

Hello,

I followed this tutorial to implement filter on gridbuttoncolumn:

http://www.telerik.com/community/code-library/aspnet-ajax/grid/filtering-and-sorting-for-gridbuttoncolumn.aspx

But When I click on the filter button I get the following error:

Telerik.Web.UI.ParseException: Expression expected    at Telerik.Web.UI.ExpressionParser.ParsePrimaryStart()     at Telerik.Web.UI.ExpressionParser.ParsePrimary()     at Telerik.Web.UI.ExpressionParser.ParseUnary()     at Telerik.Web.UI.ExpressionParser.ParseMultiplicative()     at Telerik.Web.UI.ExpressionParser.ParseAdditive()     at Telerik.Web.UI.ExpressionParser.ParseComparison()     at Telerik.Web.UI.ExpressionParser.ParseLogicalAnd()     at Telerik.Web.UI.ExpressionParser.ParseLogicalOr()     at Telerik.Web.UI.ExpressionParser.ParseExpression()     at Telerik.Web.UI.ExpressionParser.ParseArguments()     at Telerik.Web.UI.ExpressionParser.ParseArgumentList()     at Telerik.Web.UI.ExpressionParser.ParseIif()     at Telerik.Web.UI.ExpressionParser.ParseIdentifier()

Could you please Help on this.

PS: my version of Telerik is 2010.1.415.35

Just one more thing about it,

When I set EnableLinqExpressions = "false", there is no more error, but nothing is filtered.

Thank you

Hello Jean-Marc,

I have tested the Code Library project you have referenced and it worked as expected on my side. Please ensure that you are using the "-AJAX" version among the attachments.

For you convenience I am attaching the project converted for .NET 35.

I hope this helps.
